The spindles ofthe fiber processing machine are divided into two groups carried byspindle mounting means in the spinning apparatus. Those of one group liein bobbin winding positions in the spinning apparatus while those of theother group lie in cheese winding positions of the combined machine.Means is provided for moving the cheese winding apparatus along theframe of the machine and for delivering to it to be wound into a cheeseyarn drawn from the bobbins located in the cheese winding positionsWithout removal of the bobbins from the spindles carried by the spindlemounting means of the spinning apparatus.

This invention relates to an apparatus for forming cheeses by the directwinding of full bobbins without doffing operation in fiber processingmachines such as spinning frames and twisting machines.

Generally, in spinning frames or twisting machines (hereinafter referredto as fiber processing machines), full bobbins are first dotfed from thespindles and then placed on an automatic winder (hereinafter referred toas automatic winding machine) for forming cheeses. Thus, much time andlabor and required for this dofling operation. Further, in order toplace full bobbins on the automatic dotfing machine, it is require-d totransport the full bobbins to such machine. It is also required toinsert the full bobbins one by one onto the spindles of the automaticwinding machine, which requires further time and labor. Moreover, in theknown system, fiber processing machines and automatic winding machinesare separately installed, so that much space is required, with theincreased cost of installation. 1

Another system recently developed is known wherein an automatic windingmachine is arranged to be movable in front of and along a fiberprocessing machine, and besides the ring rails inherent to the fiberprocessing machine, exchange rails are additionally provided forinserting full bobbins thereinto, whereby yarns on the full bobbins onsaid exchange rails are wound into cheeses by the automatic windingmachine moving along the fiber processing machine. However, this systemonly incorporates an automatic winding machine into a fiber processingmachine with the view to decreasing the floor space required forinstallation of the automatic winding machine and the labor oftransportation of full bobbins. Thus, full bobbins on the side of thespindle rails as produced by the twisting and winding operation of thefiber processing machine still have to be removed to the exchange railseither manually or by an expensive and complicated automatic bobbinexchanger. Thus, the problem of bobbin exchange is left unsettled, stillrequiring labor or troublesome automatic bobbin exchangers.

The present invention eliminates the aforesaid drawbacks and providesimprovements wherein a large number of spindles mounted on the spindlerails on a fiber 3,391,527 Patented July 9, 1968 processing machine aredivided into two groups, each spindle group being in exchangeablerelation to the other so as to be capable of being positioned either inthe drafting, twisting and winding regions or twisting and windinregions or in the cheese winding regions of the fiber processingmachine, the latter machine performing its drafting, twisting andwinding operation or twisting and winding operation on the empty bobbinsof the spindle group positioned in said drafting, twisting and Windi gor twisting and winding regions, the full bobbins of the other spindlegroup being treated, without being dofifed, by an automatic windingmachine travelling in front of and along the fiber processing machinefor forming cheeses, it being so arranged that when the bobbins of onespindle group positioned in the drafting, twisting and winding regionsor twisting and winding regions have become full, the yarns on the fullbobbins of the other spindle group have also been completely wound intocheeses, whereupon the two spindle groups are exchanged at a time, theaforesaid operations being then repeated.

Since the invention is thus arranged, it is possible to omit theconvention-ally indispensable dofiing operation and preclude thenecessity of transporting full bobbins to automatic winding machines,hereby saving time and labor heretofore required for dofiing operation,and eliminating the use of complicated automatic bobbin exchanger. Hencethe invention can promote the efiiciency of textile operation. K

On the premise that yarn knotting operation can be automatically carriedout if use is made of a full automatic winding machine and that the timerequired for said winding machine to wind the yarn of one full bobbininto a cheese is much less than the time required for completing onefull bobbin, it is possible to set the treating power of the automaticwinding machine, i.e., the number of the full bobbins which it can treatto form cheeses during the time required for completing one full bobbin,so that if the full automatic winding machine is allowed to run step bystep so as to treat said set number of full bobbins in a predeterminedtime, cheeses can be continually produced one by one each time aftereither one group of spindles have completed the formation of fullbobbins once or twice.

In order to decrease the number of dofling and donning operations and ofoperators, there has heretofore been a tendency to increase the amountof yarn per bobbin. According to the present invention, it is no longernecessary to take the trouble to produce such increased full bobbins,since no operator is required for dofling and donning operations. As amatter of course, the diameter of the rings of fiber processing machinescan be decreased as well as the lift, so that by frequently repeatingthe formation of small full bobbins, it is possible to speed up fiberprocessing machines to promote the efiiciency of textile operation.

Moreover, according to the invention the promotion of the efliciency oftextile operation is further assisted by the fact that the drafting,twisting and winding operation effected by fiber processing machines andthe cheese Winding operation effected by automatic winding machines canbe concurrently and repeatedly carried out.

Further, according to the invention, without the need of exchangingbobbins on the side of fiber processing machines and automatic Windingmachines, the same effect of bobbin exchange as before can be expectedsimply by exchanging the positions of two spindle groups at apredetermined time. Consequently, the troublesome bobbin exchange can beentirely avoided.

The invention will now be described with reference to the accompanyingdrawings. Although the following description is given with reference toan instance in which the invention is applied to a spinning frame, asimilar construction may be made in accordance with the invention incase of a twisting machine.

Referring to the drawings, in FIG. 1 is shown a method of dividing anumber of spindles into two groups and alternately positioning the thusgrouped spindles in drafting and winding sections corresponding to draftroller mechanisms and in cheese winding sections operated by automaticwinding machines. In other Words, a number of spindles 2 laterallydisposed on a frame 1 are divided into a first group of spindle 2 in oddnumbers and a second group of spindles 2" in even numbers. The oddnumbered and even-numbered spindles 2, 2" are separately driven by driveshafts 3, 3', respectively, journalled in parallel to the frame. It willbe noted that in such a kind of spinning frame, spindles are arrangedcorrespondingly to each other on both sides of the frame 1. Thus,spindles in odd or even numbers on one side are associated in pairs withthose in odd or even numbers on the other side. Such pairs can bedivided into two groups in connection with different power sources bydrivingly associating them with respective drive shafts 3, 3' as bytapes 4, 4', as shown in FIGS. 1 and 2. The draft roller mechanisms 5 ofthe spinning frame are of known construction, and are mounted on thespinning frame members F with twice the spindle pitch, i.e. as shown inFIG. I the draft rollers 5 are spaced twice as far apart as the adjacentspindles 2' and 2". It is necessary that these draft roller mechanismsbe so arranged on the frame F as. to correspond to either theeven-numbered or the odd-numbered spindle group carried by frame 1.These two spindle groups 2' and 2", their two drive shafts 3, 3', andthe clutches and power source to be later described are so constructedthat they may be integrally moved a half the roller pitch either to theright or to the left at the predetermined time by movement of frame 1 onwhich they are mounted relative to frame members F on which the rollers5 are mounted, by any suitable means (not shown). Further, these twodrive shafts 3 and 3 are connected to a single power source (not shown)through clutches for the change of drive (not shown). The change ofdrive is such that when one drive for a first spindle group which nowconfronts or corresponds to the draft roller mechanisms is being driven,the other drive shaft for the other or second spindle group which nowconfronts or corresponds to the cheese winding regions is indisengagement from the power source. Thus, the spindle groupcorresponding to the draft roller mechanisms is rotated at a high speed,thereby allowing the spindles to effect the usual drafting and spinningoperation in cooperation with the draft roller mechanisms, while theother spindle group deviated from said draft roller mechanisms is in astationary condition and hence the yarns on the full bob-bins on thesespindles are stationary so that they will be successively wound intocheeses by means of automatic winding machines travelling stepwise alongthe spinning frame.

In this spinning frame embodying the invention wherein spindles arrangedin rows are divided into two groups by the relation of odd and evennumbers, the object of simultaneously effecting the drafting and windingoperation and the cheese winding operation requiresthe provision of aring rail which is different from known one. That is to say, fordrafting and winding, it is necessary to raise and lower spindle railsalong bobbins. On the other hand, at the cheese winding regions adjacentthe draft roller mechanisms, such ring rail constitutes an obstacle,which is required to be removed. Thus, the ring rails used herein shouldbe of such a structure as to meet the above-mentioned conditions. Onesuch statisfactory form of ring rail 6 is shown in FIGS. 1 and 4. Asshown, it is composed of a ring rail base body 6' disposed inside thespindle rows to extend along the full length of the frame and verticallymovable, and ring support plates 6" outwardly projecting therefrom tocorrespond to the draft roller mechanisms. The ring support plates 6"are fitted with rings 7 including travellers. With the arrangement thusmade, it is possible to effect the building motion of the ring rails atthe draft roller mechanism and simultaneously effect the two distinctoperations, i.e. a drafting, twisting and winding operation and a cheesewinding operation, with the spindles of the two groups maintained in arow on either side.

In FIG. 3 the left half shows the drafting, twisting and winding regionsoperated by the roller draft mechanism while the right half shows thecheese winding regions operated by the automatic winding machines. Insuch drafting, twisting and winding regions it is required to providemeans for separating yarns connected to full bobbins therefrom when thetwo spindle groups are to be exchanged and for winding the thusseparated yarns extending from the draft roller mechanisms around theirrespective empty bobbins newly supplied to the drafting, twisting andwinding regions.

The means will now be explained. As shown in FIGS. 3, 4 and 5, eachdrafting, twisting and winding region is provided with an arm body 11adapted to press down a spun yarn 9 to press down a spun yarn 9 to causethe latter to cross a yarn gripper body 10. Such arm bodies are securedto a common shaft 12 in such a manner that they may correspond to theirrespective drafting, twisting and winding regions and be positionedsomewhat laterally of the spindles. A rod 13 is provided at the free endof each arm body so as to cross said spun yarn for pressing down thelatter upon the falling-down of the arm body.

The yarn gripper 10, which serves to temporarily grip the spun yarnspressed down by the arm bodies, is so mounted that it is positioned infront of the spindles and somewhat below yarn holder bodies 14 rigidlysecured to the spindles. The yarn gripper body 10 is in the form of anelongated bar extending along the full length of the frame and iscomposed of fixed and movable rods 10' and 10", respectively, contactedwith each other at their side surfaces and adapted to be shiftable tochange their relative position, as shown in FIGS. 6 and 7. Further, itis provided with recesses 15 and 15 on the upper surfaces of both rodsat the places thereof corresponding to the drafting, twisting andwinding regions. Blocks 16 are fitted in said recesses to stride thelatter, said blocks being rigidly secured to the movable rod by means ofbolts 17. FIG. 6 shows a condition in which the spun yarn is notgripped, while FIG. 7 shows another condition in which it is gripped.Though not shown in FIGS. 6 and 7, guide plates 18, 18 for spun yarnsare rigidly secured to the fixed rod of the yarn gripper body 10, onboth sides of the recesses, as shown in FIGS. 4 and 5, in order that thespun yarns, when pressed down by the arm bodies, may be positivelyguided to cross the recesses of the yarn gripper body. Yarn transferbodies 19 which serve to cause the spun yarns extending between the yarngripper body and the draft roller mechanisms to be seized by emptybobbins are provided in front of the yarn gripper body. These yarntransfer bodies are mounted on a transverse rod 20 extending along thefull length of the frame so as to correspond to the drafting, twistingand winding regions and are normally held in a condition shown in solidlines in FIGS. 3 and 4. The transverse rods are supported by and betweentwo arm bodies 21 having their root portions pivoted to the frame. Thus,when the yarn gripper body 10 grips the spun yarns and new bobbins aresupplied to the drafting, twisting and Winding regions, the yarntransfer bodies are swung forwardly by the swing movement of the armbodies 21, thereby supplying the spun yarns connected between the yarngripper body and the draft roller mechanisms to the yarn holder bodies14 at the roots of the spindles. The structure of such yarn holder bodyrigidly secured to the root of a spindle is shown in FIGS. 8 and 9. Itconsists of a circular plate 24 having a hub sleeve 22 to be rigidlysecured to the root of a spindle and two or three grooves 23 equispacedon the surface. These grooves are so arranged as to extend in thedirection of the rotation of the circular plate, and receive therein thefront ends 25 of plate springs 25 as shown in FIGS. 10. The roots of theplate springs are rigidly secured to the peripheral upright edge of thecircular plate. Thus, the spun yarn can be held between the front end25' of the plate spring and the inner wall 23' of the grooves.

The operation of the present invention is as follows.

When the drafting, twisting and winding operation of one group ofspindles is completed to provide full bobbins in a condition shown onthe left-hand side of FIG. 3, the ring rails are lowered at a high speedto the lowermost level as shown in FIG. 5, and the spun yarns are woundtwo or three turns around the lower portions of the full bobbins,whereupon the group of spindles are simultaneously stopped. At thistime, the cheese winding operation shown on the right-hand side of FIG.3 has just been completed also. Thereafter, the ring rails are raised ata high speed to a position free from interfering with the successiveoperations, i.e., a position shown in dot and dash lines in FIG. 3.After the ring rails have been raised to the predetermined level, thearm bodies fall down to a position shown in dot and dash lines in FIGS.3 and 5, thereby causing the spun yarns to cross the recess of the yarngripper body. Simultaneously therewith, the yarn gripper body isactuated to grip the crossing portions of the spun yarns as shown inFIG. 7. In this condition the group of spindles carrying thereon fullbobbins are simultaneously rotated one or two turns thereby cutting offthe spun yarns between the yarn gripper body and spindles. In so doing,the arm bodies 11 are returned to the solid line position shown in FIG.3. Upon the completion of the cutting of the spun yarns, the two spindlegroups are simultaneously moved in a predetermined direction by /2roller pitch, so that the full bobbin-carrying spindles are positionedin the adjacent cheese winding regions, while the empty bobbins whichwere positioned in the cheese winding regions are now positioned in thedrafting, twisting and winding regions. That is to say, the two spindlegroups exchange their positions. In this condition the yarn transferbodies in front of the yarn gripper body advance towards thecorresponding spindles thereby to press down the spun yarns connectedbetween the yarn holder bodies and the draft roller mechanisms againstthe lower portions of the yarn holder bodies below the spindles, andthen said group of spindles are simultaneously rotated one or two turns,whereupon the yarns are inserted into the grooves of the yarn holderbodies which, in turn, positively grip the spun yarns. At the same time,the spun yarns are released from the yarn gripper body, and then thering rails are again lowered to the lowermost position, whereupon thegroup of spindles in the drafting, twisting and winding regions aresimultaneously driven, so that the next drafting and spinning operationis started. Concurrently with the drafting, twisting and windingoperation, the automatic winding machines associated with the framebegin cheese winding operation. In addition, on either side of the frameare provided rails 27 and 28 extending along the full length of theframe for the auto matic winding machines 26, as shown in FIG. 3.

Now, the reason why a series of drafting-winding and cheese winding canbe smoothly effected by such concurrent operations, namely, drafting,twisting and winding operation effected by the spinning frame and cheesewinding operation effected by the automatic cheese winding machine, willbe described by showing an example. Supposing, for example, that theyarn delivery speed of the spinning frame is 30 m./min. and the windingspeed of the automatic winding machines is 800 m./min., it suffices thatone automatic cheese winding machine has charge of full bobbins, about24 in number calculated as an approximate value of 800/30. On the otherhand, the Weight of a cheese is generally of the order of 1.8 pounds.Thus, if the amount of the yarn on a full bobbin is adjusted to about0.037 pound, it is possible to produce one cheese from 48 full bobbins.That is to say, it is possible to produce one cheese by allowing anautomatic winding machine to execute one reciprocation per 24 spindles.Therefore, it is seen that it suffices for this purpose to provide suchautomatic winding machines on either side of the frame with a ratio ofone machine per 24 spindles. It is to be understood that the numericalvalues given above are only by way of example, and that other variouscombinations may be obtained as desired based upon the aforesaidprinciple by suitably determining the weight of one cheese and theamount of the yarn on one full bobbin. 7

FIG. 11 shows another embodiment of the invention, wherein two spindlegroups 29 and 30 are adapted to be driven by a single tape 31. Thus, ofthe spindles arranged in a row, those located at odd numbers form onegroup and those located at even numbers form the other group, theexchange of the positions of said spindle groups being effected in thesame manner as the first embodiment by simultaneously shifting allspindles a half the roller pitch in one direction. Thereafter, thespindle group which is deviated from draft roller mechanisms 32 will besomewhat tilted outwardly away from the tape. This tilting mechanismwill be described with reference to FIG. 12. Plates 54 each supporting aspindle are arranged on the frame, said support plates being hinged at55 so that they may be tilted relative to the frame at a predeterminedtime. Fixedly positioned below the front end portions of these supportplates is a cam plate 56 provided with raised portions 56' at the placesthereof confronting the draft roller mechanisms. Thus, those supportplates which ride on said raised portions are in lifted position asshown in FIG. 12, so that the spindles supported thereby are indrafting, twisting and winding condition and the spindle wharves are, ofcourse, in contact with the tape, which is supported for driving thespindles, as aforesaid, by any suitable tape supporting means (notshown) e.g. of the known form shown in DAS 1,066,112 published by theGerman Patent Ofiice Sept. 24, 1959. On the other hand, the othersupport plates positioned in the cheese winding regions are forwardlytilted against the recesses 56" of the cam plate, so that thecorresponding spindle wharves are out of contact with the tape and instopped position. In this condition, cheese winding operation is carriedout. It will be seen that if the base member on which are mounted thesesupport plates is moved by A2 roller pitch, the as-raised and as-loweredsupport plates will be lowered and raised by the recesses and raisedportions of the cam plate, all respectively. In short, the group ofspindles confronting the draft roller mechanisms are contacted with thetape, are rotated at a high speed, and perform the intended drafting andspinning operation in cooperation with the draft roller mechanisms,while the other spindles are in stopped position so that the yarns onthe full bobbins carried by these stopped spindles are Wound intocheeses by the automatic winding machines. The other arrangements ofthis embodiment are the same as the first embodiment.

FIGS. 13 through 16 show a further embodiment, wherein spindles arearranged in two rows, front and rear, on each side of the frame, saidfront and rear rows each forming one group. After the lapse of thepredetermined time, the pairs of spindles are simultaneously to tatedthrough 180 whereby the positions of the two groups of spindles areexchanged. This will be described in more detail with reference to FIGS.13 through 16. Spindles 33 and 34 are arranged in two rows on each sideof the frame, the outer spindle group 33 being posi- 1 tioned on thecheese winding region side, the inner spindle group 34 being in aposition to cooperate with the draft roller mechanism 35, all thespindles of the group 34 being in contact with a single tape 36 anddriven at a high speed. This will be further described with reference toFIG. 14. A spindle rail 37 is provided with as many bearing sleeves 38as the spindles of one group vertically extending therefrom and arrangedat fixed intervals. Shafts 40 for spindle support plates 39 arerotatably fitted in said bearing sleeves. The spindle support plates arein the form of elongated plates having said shafts secured to the middleportions of the lower surfaces thereof and are supported on the uppersurfaces of the bearing sleeves. Pairs of bolsters 41, 42 are secured tothe spindle support plates at their opposed end portions equidistantfrom the axes of the shafts 40, each pair receiving therein a pair ofspindles. The spindle support plates are so placed that these pairs ofspindles may be positioned in front and rear relation as shown in thefigure. That is to say, two spindle rows, front and rear, are providedon the spindle rail. In this condition the spinning frame is run to windspun yarns 43 onto bobbins 44. When the bobbins become full, the machineis stopped, whereupon the spindle support plates are turned through 180,thereby effecting the positional exchange between the full bobbins inrear row and empty bobbins in front row. This means that the fullbobbins assume the front row position and the empty bobbins assume therear row position to cooperate with the draft roller mechanisms. Inthese conditions, spinning and winding operation is again effected atrear row and concurrently therewith the automatic winding machinesprovided in front of the spinning frame draw yarns from the full bobbinsin front row and wind them into cheeses. Each of the shafts of thespindle support plates has a worm wheel 45 secured to the lower endthereof. These worm wheels mesh with corresponding worms 47 mounted on acommon shaft 46. Thus, by rotating the common shaft, all the spindlesupport plates are rotated through 180 to exchange the positions of thefront and rear spindle rows at a time. In this case, if it is soarranged that all the spindle support plates are rotated at a time, itwill be apparent from FIG. 15 that the distance between each pair ofspindles must be relatively long. For the purpose of decreasing suchdistance, it may be so arranged that half the spindle support plates,positioned at every second place, are simultaneously rotated by likeworms 47A carried by a common shaft 46A, followed by the nextsimultaneous rotation of the other by like worms 47B carried by a commonshaft 4613, thereby completing the positional exchange of the front andrear rows at two times, as shown in FIG. 16. With this arrangement, thespindle distance can be shortened. In addition, in effecting thepositional exchange of the two groups, the above-mentioned thirdembodiment also must be provided with means for cutting the spun yarnsoff their full bobbins and winding the thus separated yarns around theempty bobbins supplied to the drafting, twisting and winding regions.Unlike the first embodiment, in this case the arm bodies for pressingdown yarns are positioned in front of the spindles, while the yarngripper body and yarn transfer bodies are positioned at the rear of thespindles. With this arrangement, it is possible to smoothly perform theprocedures at the time of the bobbin exchange in the same manner as thefirst embodiment.

In addition, in the drawings, 48 designates a sliver bobbin; 49, 50snail wires; 51 the dram of the automatic winding machine; 52 a cradle;and 53 a cheese.
